Ahh, ok - that makes it easier. You're in for a treat, I love Poly CL.
You'll be in the Hawaii building. All Garden View rooms face south towards the Oasis Pool/courtyard. See the yellow outline on the map below over the Hawaii building - all the GV rooms are on this side. The other side has TPV and LV rooms. NOTE - this map for some reason does not show the Oasis Pool. That big green courtyard is actually the Oasis Pool and Bar/Grill. It's very new and fantastic, in my humble opinion.
As you can see, one GREAT attribute about the Hawaii longhouse is that you're just steps from both pools.

For room requests, I would focus on the floor. All first floor rooms have walk out patios, third floor rooms have walk-out balconies. The second floor does NOT have balaconies, only a balcony door that opens to an immediate railing. 9 out of 10 people generally don't want a second floor room given the lack of balcony, so you'll find most folks request to either be on the first of third floor. Personally I like being on the third floor just to not have noise above me, but that's not that important.
The CL lounge is on the left side of the Hawaii building when looking at that map above. The main CL lounge is on the second floor with a smaller seating area on the third. All floors are connected via a convenient stairwell or escalator.
Other than the floor and proximity to the lounge, all of the rooms are pretty much identical with only small variations in the view from your room. Some rooms have a more open view of the pool than others, some may be more obscured by trees or plants.
I was just down there in Feb and posted a bunch of room and lounge pics over on the CL thread if you want to go search over there.
Have fun!
